Be it known that I, GEORGE P. BOSWORTH, a citizen of the United States,residing'at Pawtucket, in the State of Rhode Island, have inventeda newand useful Improvement in Stop- Motions for Spoofing-Machines, of whichthe following is a specification; My invention consists in an improvedcombination of parts whereby upon the breaking or failure of one of thethreads the fallen drop- Wire will be automatically returned to itsraised position, in which the eye of'the dropwire can be readilythreaded forthe continued operation of the spooler.

In the accompanying drawings, Figure 1 represents the side view of astop-motion provided with my improvement. Fig. 2 represents the top viewof the same. Fig. 3 represents the side view, as in Fig. 1, with one ofthe threads broken and its drop-wire fallen to its lower position. Fig.4 represents the same side view with the eye of the drop-wire returnedto its former position preparatory to threading. Fig. 5 represents asection taken in the line 5 5 of Fig. 1. Fig. 6 represents a sectiontaken in the line 6 6 of Fig. '5 when the several parts of the mechanismare in the position shown in Fig. 1. Fig. 7 represents the same sectionwhen the several parts are in the position shown in Fig. 3. Fig. 8represents the same section when the several parts are in the positionshown in Fig. 4:. Fig. 9 represents a section taken in the line 9 9 ofFig. 5 when the several parts are in the position shown in Fig. 1. Fig.10 represents an end elevation. Fig. 11 represents a side view of thetripping-lever removed from the machine.

In the drawings, A represents the frame of the spoofing-machine; B, thestep-rail; C, the bolster-rail; J, the spindle, and K the traverse-bar.

To the bolster-rail G is attached the frame D, which supports thestop-motion mechanism, the said frame being provided with an uprightstud, upon which is placed the loose sleeve E, which is operated to turnin one dicatch-lever F, which" is provided with the hand-operated knobh. I

To the upper end of the sleeve E at the screw 2' is pivoted the arm G,whichis made capable'of adjustment by means of the slot j in the arm Gand the tightening-screw It in the sleeve, and the said arm Grisprovided with the screw-stud Z, having a head m, which by contact withthe rounded head a of the spool H serves to raise the same from itssupporting-disk 0, as shown in Fig. 4. The outer end of the arm G isprovided with the friction-heady], made of rubber or other suitablematerial, adapted by pressing against the edge 9 of the head a of thespool to check the momentum of the same upon the disengagement of thegravitating catch-lever F from the catch I. The catch I is loosely heldupon the pivot-stud r at the outer side of the frame D, and from theinwardly-projecting stud r of the catch I connection is made to thetripping-lever s by means of the connecting-rod m, the saidtripping-lever s and the drop-wires t t 25 being pivoted upon the fixedrod u, which extends from side to side of theframe D. The catch-lever Fis attached to the projecting outer end of the rockshaft 2:, and to theopposite end of the said shaft outside of the frame is secured theweighted arm 00, the wiper-arm w being also attached to the said shaftwithin the frame. The several threads w are made to pass through theeyes a of the drop-wires t and thence to the spool H, the saiddrop-wires when the several threads are intact being held in theirelevated positions, as shown in Fig. 1, and upon the breaking or failureof one of the threads w the downward projection 25' of the disengageddrop-wire t by striking against the bar 8' of the tripping-lever s willcause the disengagement of the gravitating catchlever F from the catch Ito cause the instantaneous stopping of the movement of the spool Hwithout requiring the stopping of the spindle J, upon which the spool issupported, the said spool being first raised from the driving disk 0 bymeans of the swinging movement of the head m, caused by the resilienceof the spring 6, and then frictioned by the engagement of thefriction-headp with the edge (1 of the head at of the spool. When thefriction-head 12 has engaged with the edge of the head of the spool, thecontinued movement of the catch-lever F to the position shown in Fig.4will cause the movement of the connecting-rod f loosely through theperforation in the outer end of the arm 01 and will also cause theupward movement of the disengaged drop-wire t by the resultingengagement of the wiper-arm w with the side of the tripping-lever 5,thus causing the automatic return of the said drop-wire to its formerposition, in which the eye 4) can be readily threaded, after which uponthe upward movement of the catch-lever F by the be brought into lockingengagement with the catch I, as before, for the continued winding of thethread upon the spool.

I have preferably illustrated my improvement in connection with thestop-motion device for which I obtained Letters Patent of the UnitedStates, No. 575,663; but the improvement herein set forth for returningthe drop-wire may be employed in connection with other devices forstopping the spool.

I claim as my invention- In a stop motion for spoofing-machines, thecombination of the rotating spindle, and means for stopping the rotationof the spool while the spindle continues its revolution, with thedrop-wires, the tripping-lever, the catch operatively connected with thetripping-lever, the catch-lever retained in its elevated position bymeans of the catch, the operative connection between the catch-lever andthe spoolstopping means, the wiper-arm, and operative connection betweenthe catch-lever and the wiper-arm, whereby upon the tripping of thecatch-lever the wiper-arm will serve to cause the return of the fallendrop-Wire to its position for threading, substantially as described.
